COMBINED HEAT AND STEAM GENERATOR.

Specification of Letters Patent.

Patented Oct. 23, 1917.

Application filed June 4, 1917. Serial No. 172,611.

To all whom it may concern:

Be it known that I, HOMER V. CLUTTER, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Combined Heat and Steam Generators, of which the following is a specification. y

This invention relates to an apparatus for utilizing water, liquid fuel and air and gaseous fuel for generating an expansive element for use in driving machinery, heating buildings or other useful purposes, and has for its object, broadly, to provide a construction which will consist of few and simple parts, will economically produce superheated steam, will utilize the force of expanded air and exhaust gases as well as steam and will occupy a limited space in proportion to the degree ofheat and quantity of steam generated, as compared with other means.

the boiler by any suitable means, as by brackets 9 and a pipe-section 10. At one 7 end of the combustion chamber and communicating' therewith is a sleeve 11 which traverses the wall of the boiler, the outer end of said sleeve being provided with a screw-plug 12.

The screw-plug is provided with an intake pipe 13 for admitting air under pressure to the chamber 7, the degree of said air pressure being greater than the degree of steam pressure in the boiler. Numeral 14:

. indicates a pipe for the intake of liquid fuel under pressure, said pipe extending within and having its convergent discharge terminal disposed adjacent to the end of the pipe 13. I

The container 8- is provided with a verticallydisposed conducting pipe 15, its upper The invention includes a container for ignited hydrocarbon to produce heat and expanded gases, said container being disposed in and surrounded by a water receptacle, whereby steam will be generated and the heat of the container conserved.

The invention consists of the novel-construcend terminating above the water-level of the boiler and preferably projecting upwardly within the dome, the lower end of said conducting pipe being in communication with the chamber 7 and the pipe sectiOn 10, and, preferably, disposed in line with and terminating near the end of said pipe-section.

At 16 is indicated a valve-housing having a valve seat 17 and a valve 18, said valvehousing being threaded on a tubular part 19 which is threaded in the pipe-section 10';

andat 20 is indicateda line pipe normally in communication with the chamber 21-0f the receptacle 5 and chamber 7, subject to Fig. 2 is a view in is a sectional view through the screw-plug for the fuel intake and sleeve of the com-' 'its upper part being provided with a dome 6.

Disposed within the boiler is a combus' tion chamber 7, its wall 8 being supported by and malntained above the bottom of the control of the valve 18. v

Any suitable means may be employed for igniting the hydrocarbon in the combustion chamber, the means shown herein being the spark-plug 22 which is mounted in the screw-plug 12, said spark-plug being operated by any suitable" source of electrical supply, one of its electrical conductors being indicated at 23.

. On account of the water-sealed connection of the conducting" pipe 15 with the upper part of the Wall 8, water fromU-the chamber .21 will not enter the combustion chamber, and it is obvious that the heat generated in said chamber will not be directlylost-to the atmosphere by radiation. Water is supplied to the receptacle 5 means of the supply pipe 24.

. within said chamber.

In operation, air compressed by any suitable means is introduced to the chamber 7, the degree of. compression of the air being suficienhto cause it to pass the check valve 25 and pipe 13 against the resisting pressure of steam and expanded elements Liquid fuel under pressure lwillsalso pass the check. valve 26 and will be atomized or finely divided when it passes through the convergentte'rminal of the. pipe 14. The hydrocarbon within the chamber 7 will be ignited, and the combustion will cause steam to be generated.

The valve 18 being open, steam will pass from the dome through the pipe 15, pipesection and line-pipe 20 for driving machinery or for heating purposes.

During operation, after the hydrocarbon in the chamber 7 is ignited, combustion will continue. without interruption, the chamber being supplied with air and liquid fuel, as first described. The heated exhaust gases will move from the chamber 7 to pipe 20 with the steam and will become intermixed therewith while passing through the pipesection 10, and it will be-understood that, on account of the heat in the combustion chamber the pipe 15 will become intensely heated. The steam will be exposed to the heat of pipe 15 while being conducted therein and will be superheated, the "construction being suchthat the'steam will be conducted communicating with and having its intake disposed above the vwater receptacle and having its discharge port disposed within the combustion chamber adjacent to the pipe section, and devices for igniting the contents of the combustion chamber.

2. Ina combined heat and steam generator, the combination of a line pipe, a water receptacle provided with a dome, a combustion chamber below the dome within the receptacle, said chamber having an intake for compressed air, an intake for liquid fuel under pressure and having a pipe-section communicating with the linepipe, devices for igniting the contents of said combust on chamber, and an upright conducting pipe I in communication with the combustion chamher and with the dome oi the water receptanaeaera cle, said conducting pipe being disposed in line with the ipe-section.

3. In a com med heat and steam generhaving an intake for compressed air and an intake for liquid fuel under pressure, a conducting pipe disposed in line with the pipesection and having its intake terminal disposed in said dome, its discharge terminal being disposed near the lowermost part of the combustion chamber, adjacent to said pipe-section.

4. In a combined heat and steam generator, a water receptacle, a second receptacle for containing ignited hydrocarbon, said second receptacle being provided with intake pipes and being disposed within the water receptacle for converting the water into steam, a line pipe, a pipe-section communicating with the second receptacle and the line pipe, and an upright pipe for conducting steam from the water receptacle to the second receptacle for a movement of steam to the line pipe by moving through the pipe-section, said upright pipe having an imperforate wall throughout its entire length and having its intake disposed above the water receptacle.

5. In a combined heat and steam generator, a water receptacle, a second receptacle for containing a heating element, said sec- L 0nd receptaclebeing disposed within and I surrounded by the walls of the water receptacle for converting the Water into steam, tubular members traversing the wall of the water receptacle for conducting fluids under pressure to the second receptacle, a line pipe, a pipe-section having a un'forrn bore in communication with the second receptacle and the line pipe, and an upright pipe having its intake disposed above the water re- 4 ceptacle and traversing a wall of and er tending substantially through the second receptacle for conducting steam from the water receptacle to discharge it at the lower part of the second receptacle for a move 7 ment thereof to the line pipe by passing through the pipe-section I 6. In a combined heat and steam generator, a receptacle for containing water and provided with a dome, a second receptacle for containing ignited hydrocarbon and adapted to be disposed in the water circumscribed by the walls of the first named receptacle for causing the water to be converted into steam, pipes traversing a wall of the first named receptacle for conducting fluids to the second receptacle, a line pipe, a pipe section connnunicating with the seeond receptacle and the line pipe, an upright pipe for conducting steam from said dome to the second receptacle-foia movement of said steam and the products of the ignited hydrocarbon of said second receptacle to the line pipe by moving through the pipe section, said conducting pipe being disposed substantially in alinement 'With the pipe-section, and a valve for controlling a communication of the pipe-section With the line pipe. 10
